在窗口应用程序中写入命令行

Question

我正在尝试让我的基于WinForm的C#与命令行合作,但是我很难让它发挥得很好.例如,我有这个代码:

    [STAThread]
    static void Main(string[] args) {
        foreach (string s in args) {
            System.Windows.Forms.MessageBox.Show(s);
            Console.WriteLine("String: " + s);
        }

        Mutex appSingleton = new System.Threading.Mutex(false, "WinSyncSingalInstanceMutx");
        if (appSingleton.WaitOne(0, false)) {
            try {
                Application.EnableVisualStyles();
                Application.SetCompatibleTextRenderingDefault(false);

                //start logger
                Logger.singleton.makeOpen(true);
                Application.Run(new MainForm(false));
            } catch (Exception) {
            } finally {
                appSingleton.Close();
                Logger.singleton.makeOpen(false); 
            }
        } else {
            System.Windows.Forms.MessageBox.Show("Sorry, only one instance of WinSync can be ran at once.");
        }
    }
}

它应该使用Console.WriteLine写入控制台,但我什么也看不见,只显示MessageBox.

我究竟做错了什么？

尝试AttachConsole(-1)重定向Console.Out,为我工作:

using System;
using System.Collections.Generic;
using System.Windows.Forms;
using System.Runtime.InteropServices;

namespace PEFixer
{
    static class Program
    {
        [DllImport("kernel32.dll")]
        private static extern bool AttachConsole(int dwProcessId);

        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        [STAThread]
        static int Main(string[] args)
        {
            if (args.Length > 0)
            {
                AttachConsole(-1);
                return Form1.doTransformCmdLine(args);
            }
            else
            {
                Application.EnableVisualStyles();
                Application.SetCompatibleTextRenderingDefault(false);
                Application.Run(new Form1());
            }
            return 0;
        }
    }
}
